Bad face CP? Is it true that small brown bottles, small black bottles, and fairy water cannot be used together with retinol?

Recently, many fans of

asked Xiaomei:

reported that small brown bottles, small black bottles, and fairy water cannot be used together with retinol products. Is this true? Is

mixed with ingredients to destroy the acid-base balance? This statement of sounds like that, but it is actually unreasonable. Why is

? Let's listen to the analysis of detective Xiaomei!

First of all, we need to point out a common sense error:

uses Pitera's "galactosyl yeast fermentation product filtrate" instead of the "difid yeast fermentation product" mentioned in the video. Although

are all fermented products, fairy water is different from small brown and small black bottles.

So we first remove the fairy water.

As for the coexistence of retinol and the lysate of yeast fermentation product, the answer is yes. We checked

and found that some skin care products contain both retinol and the lysate of the fermented product of difid yeast, such as the following one.

In fact, before the launch of each skin care product, the formula will be repeatedly adjusted to achieve better results.

If retinol and the lysate of the fermentation product of Difid yeast really react, I believe that formulators will not put them together.

The lysates of the fermentation product of difid yeast used in the small brown bottle and the small black bottle are all from German CLR company .

According to CLR, the pH range of the lysate of the fermentation product of Difidus yeast is 3.8-7.0, which is widely applicable.

Its tolerance to acid is far beyond our imagination, as long as it is not a strong acid environment, it can tolerate it.

and retinol is oily and insoluble in water.

So pure retinol raw materials are not acid-base, let alone damage the acid-base balance. The pure raw material of

is of this nature, will it be different when used in the product?

We also tested the pH of several products in the video. The results of

are all around 7, and the pH of products containing retinol, such as Elixir and Arden, is not particularly acidic, which is quite mild.

So there will be no problem with the superimposition of these products.

Seeing this, you should be wise to know: the rumor of

is a poisonous CP is unreasonable, how should you use it or how.

In fact, apart from raw material barrels and acid-brushing products, there is no big problem with matching and using other skin care products.

As for the collocation of ingredients in skin care products, it is more for formulators to make product recommendations, so consumers don't have to worry too much.
